Page 5: Safety Precautions
Concrete Cut-Off Saw Safety Precautions Under no circumstances should you modify the original design of the cut-off saw without the approval from the manufacturer. Unauthorised modifications and spare parts from other companies may lead to serious injury. Cutting material can generate dust and vapours which may contain harmful chemicals. Know the nature of the material being cut before using the cut-off saw. -
Page 6: Equipment
Concrete Cut-Off Saw Equipment This section explains the various safety features of the cut-off saw, how they work, and the basic inspection and maintenance that you should carry out to ensure safe operation. Anti-Vibration System Over exposure to vibrations can result in blood vessel or nerve injury to persons suffering with blood circulation problems. -
Page 7: Stop Switch
Concrete Cut-Off Saw Stop Switch The stop switch should be used to stop the engine. Start the engine and make sure that the engine stops when the stop switch is on. Muffler The muffler gets very hot during use and remains so for a short time afterwards. Do not touch the hot muffler. -
Page 8: Transport And Storage
Concrete Cut-Off Saw Transport and Storage Store the cut-off saw in a lockable area so that it is out of reach of children and unauthorised persons. Do not store or transport the cut-off saw with the cutting blade still fitted in. Fuel Safety Exercise great care when handling fuel. -
Page 9: Starting And Stopping The Saw
Concrete Cut-Off Saw Starting and Stopping the Saw Before starting observe the following: Do not start the cut-off saw without the cutting arm, belt or cutting head fitted. Otherwise, the clutch can come loose and cause personal injuries. Always move the cut-off saw from the fuelling area before starting. -
Page 10: Starting The Saw
Concrete Cut-Off Saw Starting the Saw 1. Put the cut-off saw on the ground. 2. Take hold the front handle by your left hand. Put your right foot on the lower part of the rear handle. 3. Grip the starter with your right hand, and slowly pull the starter cord out until you feel some resistance from the grip. -
Page 11: Working Instructions
Concrete Cut-Off Saw Working Instructions Only use the machine in areas with good ventilation. Carbon monoxide in the exhaust fumes causes suffocation. Cutting Technique 1. Place the cutting materials according to the illustration: 2. Always cut at full throttle. 3. Start cutting gently, do not force or squeeze the blade in. 4. -
Page 12: Blade Vibration
Concrete Cut-Off Saw Blade Vibration The blade can become out of shape and vibrate if the feeding pressure is too high or if the blade is pressed into the work piece. A lower feeding pressure should stop the vibration. Otherwise, replace the cutting blade. -
Page 13: Abrasive Discs
Concrete Cut-Off Saw Abrasive Discs Abrasive discs are not intended for use with water. If an abrasive disc is stored in humid conditions, this can cause an imbalance of the disc. Always handle the cut-off saw carefully and store it with the blade removed. -
Page 14: Cutting Blades
Concrete Cut-Off Saw Cutting Blades Cutting blades are available in two standard designs; abrasive discs and diamond blades. Never use a cutting blade at a lower speed rating than that of the cut-off saw. Never use a cutting blade for any other purpose than that it was intended for. Abrasive Discs The cutting material in abrasive discs consists of grit bonded using an organic binder. -
Page 15: Diamond Blades
Concrete Cut-Off Saw Diamond Blades Diamond blades for dry cutting are a new generation of blades that do not require water cooling. However, the blades can still be damaged by excessive heat. Let the blade cool by simply lifting the blade from the cut every 30-60 seconds and let it rotate in the air for 10 seconds to cool. ... -
Page 16: Blade Set-Up
Concrete Cut-Off Saw Blade Set-Up Check the Drive Shaft and Flanges Check that the drive shaft is undamaged. Check that the contact surfaces of the cutting blades and flanges are flat, run correctly on the spindle and are free from foreign objects. -
Page 17: Fuel Handling
Concrete Cut-Off Saw Fuel Handling The cut-off saw is equipped with a two-stroke engine and must always be operated using a mixture of petrol and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. - Page 18 Concrete Cut-Off Saw Always move the cut-off saw from the fuelling area before starting. Keep the handle dry, clean and free from oil and fuel. Clean around the fuel cap after fuelling. Clean the fuel tank regularly. ...

Page 20: Changing The Drive Belt
Concrete Cut-Off Saw Changing the Drive Belt 1. Remove the right belt guard, loosen the two screws and adjust the pulley to release the belt. 2. Remove the belt from the belt pulley. Dismantle the cutting head. Replace the belt. 3. -
Page 21: Air Filter
Concrete Cut-Off Saw Air Filter The air filter should be cleaned regularly, removing dust and dirt to avoid: Carburettor malfunction Starting problems Reduced engine power Unnecessary wear to engine parts The air filter system consists of a main filter (B), a back-up filter (A) and a reliable filter screen (C). -
Page 22: Starter
Concrete Cut-Off Saw A filter used for a long period of time can never be completely cleaned. Therefore all air filters must be replaced periodically with a new one. Insufficient care of the air filter will cause deposits on the spark plug resulting in abnormal wear to engine parts. -
Page 23: Spark Plug
Concrete Cut-Off Saw Spark Plug The condition of the spark plug is affected by: An incorrect carburettor setting An incorrect fuel mixture (Too much oil) A dirty air filter These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties. -
Page 24: Cooling System
Concrete Cut-Off Saw Cooling System To obtain the lowest possible running temperature, the cut-off saw is equipped with a cooling system. The cooling system consists of cooling fins on the cylinder: An air intake on the starter unit Air flow guide ... -
